Belt Speed
This needs to be an approximate value only. There are two ways to enter the belt speed - manual and automatic learn. The
automatic learn requires a photo eye to be present.
Manual:
Measure or calculate the belt speed and enter this value. Hint: Measure the distance an object travels during 6
seconds. Multiply this by 10 to give you the speed in distance per minute.
Example: 10 feet in 6 seconds
10 x 10 = 100 feet/min.
Automatic Belt Speed Learn:
This uses the photo eye to measure the block time produced by a known length package.
Select belt speed/learn and place an object on the belt so that it will break the photo eye beam. Then enter the package length in
inches or millimeters.
The system will calculate the belt speed.

Photo Eye Distance
Photo eye distance is the distance between the side of the detector and the edge of the photo eye (see diagram below). Usually,
photo eye distance is the same as the aperture size setting. Use the Plus and Minus keys to change the value.
NOTE: If no photo eye is used, enter ‘0’ for this value.
